Description
TECHNICAL FIELD

The technical field of this disclosure is wireless communication devices, particularly, protocol translation devices.

BACKGROUND OF THE INVENTION

Advances in electronics and telemetry have resulted in the miniaturization of personal electronic devices such that electronic devices which previously required large stationary equipment can now be worn about the person. Such electronic devices are often powered by batteries stored in a battery compartment and are able to communicate with other electronic devices in their vicinity.

Communication protocols for communication between electronic devices evolve over time with hardware and software improvements to provide faster, more reliable communication. Unfortunately, existing electronic devices are stuck with the communication protocol with which they were built. Newer communication protocols required to interact with newer external devices are often different than the original communication protocol available in an older, as-built electronic device. Although the older electronic device remains capable of performing its original function, it is unable to interact with the newer devices and to take advantage of their improvements and additional features.

It would be desirable to have a protocol translation device that would overcome the above disadvantages.

 DETAILED DESCRIPTION

FIG. 1 is a schematic diagram of a protocol translation device made in accordance with the invention. The protocol translation device fits within the battery compartment of an apparatus and translates a first wireless protocol used by the apparatus to another second wireless protocol, so the apparatus can communicate with another apparatus over the second wireless protocol.

The protocol translation device 100 is for use with a first apparatus 150 having a battery compartment 152 and communicating over a first wireless protocol, and for use with a second apparatus 170 communicating over a second wireless protocol. In this embodiment, the protocol translation device 100 includes a battery casing 110 sized to fit within the battery compartment 152, the battery casing 110 defining an interior volume 112; a translator 120 having a first antenna 122 operable to communicate with the first apparatus 150, a second antenna 124 operable to communicate with the second apparatus 170, and a translator circuit 130 operably connected between the first antenna 122 and the second antenna 124; and a battery 140 operably connected to power the translator. The translator circuit 130 is operable to translate between the first wireless protocol and the second wireless protocol, is operable to communicate with the first antenna 122 on the first wireless protocol, and is operable to communicate with the second antenna 124 on the second wireless protocol. The translator 120 and the battery 140 are disposed within the interior volume 112. In this example, the battery 140 is further operably connected to power the first apparatus 150 in addition to the protocol translation device 100.

In this example, the first apparatus 150 further includes a memory 154 operable to store programming code, a processor 156 operably connected to the memory 154, and a communication interface 158 operably connected to the processor 156. The processor 156 is responsive to the programming code stored in the memory 154 to send and receive wireless signals conforming to the first wireless protocol from the communication interface 158. The processor 156 of the first apparatus 150 can be any processor desired for a particular application. Exemplary processors include a central processing unit and a microprocessor. The processor can include or be attached to auxiliary equipment, such as memory, data storage, additional processors, input/output devices, antennas, and the like, as required to perform various functions.

The communications between the first apparatus 150 and the second apparatus 170 can be described in terms of the signals between the first apparatus 150 and the second apparatus 170. In this embodiment, the communication interface 158 of the first apparatus 150 generates a first-in signal 121 which the first antenna 122 receives and passes to the translator circuit 130. The first-in signal 121 conforms to the first wireless protocol. The translator circuit 130 receives the first-in signal 121 and translates the first-in signal 121 to a second-out signal 123 which the second antenna 124 receives and passes to the second apparatus 170. The second-out signal 123 conforms to the second wireless protocol. In this embodiment, the second apparatus 170 generates a second-in signal 125 which the second antenna 124 receives and passes to the translator circuit 130. The second-in signal 125 conforms to the second wireless protocol. The translator circuit 130 receives the second-in signal 125 and translates the second-in signal 125 to a first-out signal 127 which the first antenna 122 receives and passes to the communication interface 158 of the first apparatus 150. The first-out signal 127 conforms to the first wireless protocol.

The first apparatus 150 and the second apparatus 170 can be any apparatus which the user desires to put in communication. For example, the first apparatus 150 can be an older apparatus designed to communicate on a first wireless protocol incompatible with the second apparatus 170, which is newer and uses a more recently developed second wireless protocol. The protocol translation device 100 translates the first wireless protocol to the second wireless protocol to allow the first apparatus 150 and the second apparatus 170 to communicate.
